How are laser marking machines classified? Where are they used? What are the precautions for using them?

　　The types and characteristics of laser marking machines we come into contact with daily are different, and the application fields are naturally different. Next, let's introduce them separately. 

　　1. UV laser marking machine

　　The main working principle of the UV laser marking machine is that the bonds between atoms or molecules are broken by laser energy, and then become small molecules to gasify, and finally evaporate completely. Its main features are: by focusing on on-site performance, the influencing factors in processing are very small, and the purpose of ultra-fine marking and special material marking is realized.

　　2. Fiber laser marking machine

　　The main working principle of the fiber laser marking machine is to output the laser through the fiber laser, and then pass through the high-speed scanning galvanometer system to finally realize the marking function. Its main features are: the conversion rate is very high, and both metal and non-metal materials can be engraved. Suitable for covert areas that require a high degree of detail, but also for areas that require high depth and smoothness. Its main application areas: such as marking of hardware products, marking of glasses, clocks, plastic buttons, and marking of some medicines, food, and mobile communication equipment.

　　3. Carbon dioxide laser marking machine

　　The main principle of the CO2 laser marking machine is to expand the laser beam, galvanometer and focus, and then control the deflection of the galvanometer to achieve marking. Its main application fields are: marking some clothing, shoes and hats, marking bags, marking food, cosmetics, electronic products, etc. It can be used to mark or engrave non-metallic tea products. There are various engraving methods, such as engraving, hollowing out, cutting, etc.

　　Through the above explanation, we should find that the classification of laser marking machines is different, and the application fields are also different. Therefore, when purchasing, you must choose the right model and understand the characteristics to ensure that you can buy a practical laser marking machine.

　　We should pay attention to the use of laser marking machine:

　　1. When using the marking machine, remember not to press the laser head directly with bare hands, so as not to scratch the laser head.

　　2. It is forbidden to use sharp tools during marking, so as not to accidentally injure the laser head and adversely affect the subsequent marking effect.

　　3. When taking out the laser head, don't touch the film part, and remember that taking it from the edge of the laser head is more helpful to protect the entire laser head from damage.

　　4. When cleaning the laser head of the laser marking machine equipment, it should be cleaned in a relatively dry and clean environment to avoid damage to the lens by various other unclean water, dust and other pollutants. This tends to have a significant impact on the display performance of the end device.
